AUTOOL BT260 Car Electric Circuit Tester Power Probe Automotive Scanner Auto LED Display Voltage Digital Diagnostic Tool AUTOOL BT260 electric circuit tester is suitable for diagnostic in all 6V to 30V vehicle electrical systems. With a simple hook-up of the tool to the vehicle's battery, ACvoltagedetection, DCvoltagedetection, ResistanceDetection, DiodeTest,and Currentoverloadprotection will be available to test. AUTOOL BT260 Car Electric Circuit Tester Features : 1.[AC & DC Voltage Detection Mode]: AC detects the maximum and minimum voltage, supply frequency and duty cycle of the circuit under test. While DC volt. detection detects the voltage value of the circuit under test.2.[Resistance Test & Diode Test Mode]: It detects the resistance between the circuit probe under test and the auxiliary ground; While Diode Test can quickly test the operation of the diode aembly and determines if it is conducting.3.[Ultra Extension InspectionCable 10m ]:Covering from the front to the rear of the vehicle, you can easily inspect the entire electrical circuit system.4.[Current Overload Protection]:When the current overload, AUTOOL BT260 Automotive Circuit Tester will automatically disconnect the protection circuit to reduce unneceary loes.5.[Multi-languageoptions]:Choosefrom7languages:English,German,Spanish,French,Italian,Ruian, Portuguese6.[3-YEAR WARRANTY]: For damages caused by non-human factors, AUTOOL promise to resend parts for
